“…2,3 Thus it is clear that these early motions do not strongly depend on the alcohol structure or they do not strongly shift the spectrum. 5, 7 We thus have determined that while the length of the alcohol will not affect the final solvated spectrum, the structure (primary vs secondary) does affect the spectrum. 5, 7 It has been observed that the amount of spectral shift on solvation is independent of the length of the alcohol at room temperaturesall primary alcohols show a similar final solvated spectrum.…”

The solvation of the benzophenone anion in 1-propanol, 2-propanol, and 1-butanol has been measured over the temperature range -10 to -50°C. The initial spectra of the benzophenone anion were very similar in all three alcohols. The final spectrum of the benzophenone anion in 2-propanol is less blue-shifted (17 nm) than the spectrum of the anion in 1-propanol and 1-butanol. The activation energies for solvation are 22 kJ/mol for 1 propanol and 1-butanol and 16 kJ/mol for 2-propanol, which are similar to the energy for hydrogen bond breakage in the pure solvents. This suggests that the solvent H-bond

“…The main contribution to the interaction of polar solutes with small-molecule polar solvents is due to long range dipoledipole and charge-dipole interactions, together with hydrogen bonding in the case of protic solvents. [77][78][79] Frequently, the solute-solvent interaction in polar solvents has been described in terms of continuum models using an exponential or multiexponential dielectric response. 5,48,80 It has been argued by some researchers that due to inherent molecular nature of the solvation process, the continuum models ultimately fail to explain some important features of solvation, in particular its initial, ultrafast stage.…”

The time-evolution of the fluorescence spectrum of a dissolved chromophore excited by an ultrafast pump pulse is considered. The average value of the energy difference of the solute in its excited and ground states is used to describe the relaxation of the maximum of the transient fluorescence spectrum to its equilibrium value ͑dynamic Stokes shift, DSS͒. A simple formula for the normalized DSS is obtained which generalizes an earlier standard classical expression and includes the effect of a pump pulse of finite duration. As an example, dielectric dispersion data are used for a dipolar solute in water to estimate the quantum correction to the standard DSS expression. The correction is negligible when the frequency of the pump pulse is close to the maximum in the absorption spectrum, but a deviation from the standard formula can be expected for the pump pulse tuned to a far wing of the absorption band of the chromophore. An expression is given for this deviation.
